Bottom brackets

QB-75 square taper

With the diversity of bottom bracket design in the last decade, IRD have introduced a premium line of square taper bottom brackets, an older design which other makers are neglecting.

There are very many loyal users who trust the design, appreciate it’s merits and have beautiful square taper cranks which they have no desire or need to replace.

Most square tapers that you can find now are not of this quality – made in Japan by Tange Seiki.

Interloc offer Italian, French & Swiss cups to solve variety in European frames and replacement bearings are available too.
